In order to do this, the seats in the cab have been lowered, with bus-style see-through concertina doors on the near side. Extra windows have been installed, mirrors have been upgraded and camera systems will monitor blind spots.

The vehicles, from Mercedes-Benz, Dennis Eagle, Volvo, Scania, DAF and MAN were designed under the Construction Logistics and Cyclist Safety agreement (Clocs).

The event at ExCeL is being attended by TfL Commissioner Sir Peter Hendy, who told the Standard: “Every death and injury on our roads is a tragedy and ruins lives. At TfL we are reducing these wherever possible, and are proud to be a supporter and funder of Clocs.

“The new vehicles, with massively reduced blind spots, show what can be done if people join together for a common good to solve a simple problem.”
